Conteúdo: | Cassava (Manihot esculenta Crantz.) is an economically important crop in tropical regions, and viral diseases are main production constraints. The main objective of this study was to identify naturally occurring cassava virus X (CsVX) infections in selected cassava germplasm accessions commonly used in breeding programs in the Amazon region of Brazil. Out of 14 accessions analyzed, three showed the presence of CsVX. Comparative analysis of nucleotide and amino acid sequences within the CP region revealed the highest identities of 82.3% and 97.2%, respectively, with a CsVX sequence from Venezuela (NC_034375). Notably, this Venezuelan sequence exhibited close relationships with nearly complete CsVX sequences from Brazil, China, and Colombia, as assembled in this study. These findings provide valuable insights into the genetic diversity of CsVX and highlight the potential implications of novel potexvirus infections specifically in the cassava production context in Brazil.
